Abstract

Die Erfindung betrifft ein landwirtschaftliches Bodenbearbeitungswerkzeug mit einem Zinkenkörper (10), der einen Befestigungsabschnitt zur maschinenseitigen Befestigung und einen Arbeitsabschnitt (12) aufweist, wobei der Arbeitsabschnitt (12) an seinem, dem Befestigungsabschnitt abgewandten freien Ende eine Endfläche (11) und an dem, an die Endfläche (11) angrenzenden Arbeitsabschnitt eine Anlagefläche (13) aufweist, wobei an der Anlagefläche (13) des Arbeitsabschnitts (12) wenigsten ein Schneidelement (20), bestehend aus Hartmetall befestigt ist. Zur Verbesserung der Standzeit eines solchen Bodenbearbeitungswerkzeuges ist es erfindungsgemäß vorgesehen, dass das Schneidelement (20) mit einen Schenkel (21) vorderseitig an der Anlagefläche (13) stoffschlüssig befestigt ist, dass an den Schenkel (21) einteilig ein Ansatz (22) rückseitig angeformt ist, der die Endfläche (11) des Zinkenkörpers (10) zumindest bereichsweise übergreift, dass der Ansatz (22) stoffschlüssig mit der Endfläche (11) verbunden ist, und dass zwischen dem Schenkel (21) und dem Ansatz (22) ein Übergangsbereich gebildet ist, der den Übergang zwischen der Anlagefläche (13) und der Endfläche (11) zumindest bereichsweise überdeckt.The invention relates to an agricultural soil cultivation tool with a tine body (10) which has a fastening section for machine-side fastening and a working section (12), wherein the working section (12) has an end surface (11) on its free end facing away from the fastening section and a contact surface (13) on the working section adjacent to the end surface (11), wherein at least one cutting element (20) consisting of hard metal is fastened to the contact surface (13) of the working section (12). In order to improve the service life of such a soil cultivation tool, the invention provides that the cutting element (20) is fastened to the contact surface (13) at the front in a material-locking manner by means of a leg (21), that a projection (22) is integrally formed on the rear of the leg (21), which projection overlaps the end surface (11) of the tine body (10) at least in some areas, that the projection (22) is connected in a material-locking manner to the end surface (11), and that a transition region is formed between the leg (21) and the projection (22), which at least in some areas covers the transition between the contact surface (13) and the end surface (11).
